Effects of Biosolids on Agricultural Soils in Pennsylvania

A previous study indicated that agricultural biosolid applications increased the concentration of EPA3050-digestible trace elements in soils on Pennsylvania production farms but could not indicate potential trace-element environmental availability. This study was conducted to determine if biosolid application had altered the distribution of trace-elements among operationally defined soil fractions and the relationship of trace element concentrations in soil and crop tissues.

This fact sheet, which is part of a series on land application of biosolids, presents the results of a three-year research project that investigated how agronomic biosolids utilization has affected soil and crop quality.
